European foreword
This document (HD 605 S3:2019) has been prepared by CLC/TC 20, “Electric cables”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2020-07-01
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2022-07-01
conflicting with this document have to be
withdrawn
This document supersedes HD 605 S2:2008 and all of its amendments and corrigenda (if any).
In order to maintain the integrity of existing clause numbers, and hence avoid unnecessary amendments to
over 100 particular sections of the product HDs, the normative references are given in Annex A.
The numbering of tables and figures in this standard is not conventional. It retains the scheme as used in
HD 605 S1. This is to facilitate easier cross referencing in national sections of HD 603, HD 620 and other
compendia HDs. It also allows for continuing work to rationalize and harmonize more of these test methods in
the future, without the need for further re-numbering.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
1 General
1.1 Scope
This HD collates and specifies the test methods to be used for testing polymeric insulated and sheathed electric
cables, of rated voltage up to and including 20,8/36 kV, intended for public distribution systems, and for use in
power generating plants and sub-stations.
Test methods in this HD are additional to those already harmonized, e.g. EN 60332-1 series and EN 60811
series, and are used for testing cable types specified in HD 603, HD 604, HD 620, HD 622, HD 626 and
HD 627. In each case, these HDs give complementary information needed for the practical application to each
specific type. Therefore the present HD as such is not sufficient for carrying out and evaluating the tests on
electric cables.
Full test conditions (e.g. temperatures, durations) and/or test requirements are not specified in this HD. Such
data needed to carry out the tests is given in the particular sections.
NOTE The words 'particular section' refer throughout to the section of HD 603 or HD 604, or other HD to which
HD 605 applies, in which a particular cable type is specified.
1.2 Applicable tests
Tests applicable to each type of cable are given in the particular section, which may also state the sequence,
the frequency of test, and the possibility of repeating failed tests.
1.3 Classification of tests
The classification of tests is given in Parts 1 of HD 603, HD 604, HD 620, HD 622, HD 626 and HD 627.
1.4 Sampling
The size and number of samples are given either in this HD or in the particular HDs.
If a marking is indented in the insulation or sheath surface, the samples used for the tests shall be taken so as
to include such markings.
For multicore cables, except for the test specified in 2.1.1, not more than three cores (of different colours, if
available) shall be tested unless otherwise specified.
1.5 Test conditions
1.5.1 Ambient temperature
Unless otherwise specified in the details for the particular test, tests shall be made at an ambient temperature
of (20 ± 15) °C.
1.5.2 Tolerance on temperature values
Unless otherwise specified in the particular specification, the tolerance on temperature values quoted in the
test methods are the following:
Table 1.5.2 — Tolerance on temperature values
Specified temperature, t
Tolerance
°C K
-40 ≤ t ≤ 0 ± 2
0 < t ≤ 50 according to relevant clause
50 < t ≤ 150 ± 2
t > 150 ± 3
1.5.3 Frequency and waveform of power-frequency test voltages
Unless otherwise specified the test voltage shall be in the range 49 Hz to 61 Hz of approximately sine-wave
form, the peak ratio value/r.m.s. value being equal to √2 with a tolerance of ± 7 %. The values given are r.m.s.
1.5.4 Pre-conditioning
Unless otherwise stated the tests shall be carried out not less than 16 h after the extrusion or cross-linking,
if any, of the insulating or sheathing compounds.
2 Non-electrical tests
2.1 Dimensional measurements
2.1.1 Measurement of insulation thickness
2.1.1.1 Procedure
The thickness of insulation shall be measured in accordance with EN 60811-201. Unless otherwise specified
one sample of cable shall be taken and measurement made at three places.
Compliance shall be checked on each core of cables having up to five cores, and on the number of cores
stated in the individual specification for cables with more than five cores.
If withdrawal of the conductor is difficult, it shall be stretched in a tensile machine or the piece of core shall be
immersed in an appropriate liquid until the insulation becomes loose.
2.1.1.2 Evaluation of results
